I think the club is a very good idea. I always have a "Wellness" club in each of my saves. I usually set activities to 'Spa activities' (which includes yoga, meditating and getting massages), being friendly, use hot tub etc. The good thing about the club is that you can also filter for certain traits, if you wanted to. I'd say this is the quickest way for her to meet a random eligible bachelor other than just visiting the gym. Otherwise I would like Marcus Flex (Windenburg) or Akira Kibo (San Myshuno) for her or perhaps she could get Mitchell Kalani (Oasis Springs) into shape, who is also quite adorable.
